Chapter 01 – Sets
A set is a list of objects in no particular order; they could be numbers, letters, or even words. A Venn diagram is a way of representing sets visually.

Chapter 02 – Rational Numbers
In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p, and a non-zero denominator q. In this chapter, we will learn to represent rational numbers on a number line and perform arithmetic operations.

Chapter 03 – Decimals
Decimals are a set of numbers lying between integers on a number line. They are just another way to represent fractions in mathematics. In this chapter, we will learn about the conversion of decimals to rational numbers, the kinds of decimals, and absolute values.

Chapter 04 – Exponents
The exponent of a number says how many times to use that number in a multiplication. The laws of exponents simplify the multiplication and division operations and help to solve the problems easily. In this chapter, we are going to discuss the six important laws of exponents.

Chapter 05 – Square Root of Positive Numbers
Square root, in mathematics, is a factor of a number that, when multiplied by itself, gives the original number. In this chapter, we will learn about what makes perfect squares and will find the roots of positive numbers by considering real-life scenarios.

Chapter 06 – Direct and Inverse Variation
Variation means change. With direct variation, numbers change proportionately in the same direction, while with inverse variation, they change in opposite directions. In this chapter, we will earn how to solve direct and inverse variation problems, explore their definitions, and work examples to understand the equations and techniques for solving them. Also, we learn to find the continued ratio for two or more ratios.
0/9
Chapter 07 – Financial Arithmetic
Financial mathematics describes the application of mathematics and mathematical modeling to solve financial problems. In this chapter, we will learn about the concept of taxation, profit/markups, zakat & ushr, and how they relate to our daily life.

Chapter 08 – Algebraic Expressions
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The algebraic equations which are valid for all values of variables in them are called algebraic identities. In this chapter, we will learn to perform operations on polynomials and to factorize an algebraic equation by using identities.
0/10
Chapter 09 – Linear Equations
Linear equations are equations having variables with power 1. ax+b = 0 is an example with one variable where x is the variable, and a and b are real numbers. In this chapter, we will learn the definition, type of solutions, and how to solve these equations with one variable and two variables using different methods along with examples.

Chapter 10 – Fundamentals of Geometry
Geometry is the study of different types of shapes, figures, and sizes in Maths or real life. In geometry, we learn about different angles, transformations, and similarities in the figures. It is important to know and understand some basic concepts. We will learn about working in different numbers of dimensions, and about some of the most fundamental concepts in geometry, including points, lines, and planes.
0/7
Chapter 11 – Practical Geometry
The practical Geometry chapter will teach you about lines and to construct two-dimensional given different kinds of measurements. A quadrilateral is a closed two-dimensional shape that has four sides and four angles. Any four-sided closed shape such as square, rectangle, rhombus, parallelogram, trapezium, etc. And a closed two-dimensional shape that has 3 sides and 3 angles is known as a triangle.

Chapter 12 – Circumference, Area and Volume
This topic comes under analytical geometry and the formulas for the volume and the surface area of the sphere were first discovered by Archimedes. In this chapter, we will learn about the area and volume of two-dimensional and three-dimensional shapes.
0/6
Chapter 13 – Information Handling
Frequency distribution, in statistics, is a graph or data set organized to show the frequency of occurrence of each possible outcome of a repeatable event observed many times. And, a pie chart is a way of representing data in a circular graph. Pie slices of the chart show the relative size of the data. In this chapter, we will learn to construct the frequency distribution table, some new pie chart vocabulary, and learn to construct the pie chart to represent the data.

Math Lab Activity

– What I Do in a Day

Objective:
This activity helps students understand the properties of a circle graph using a real-life application.

In this activity, you will create a circle graph to visually represent how you spend your time during an average day. By using colors and proportions, you will show the different activities you engage in and the amount of time you allocate to each.

 

Materials Required:

  1. Activity sheet with a circle graph template
  2. Colored pencils or markers
  3. Strips of paper
  4. Glue or tape
  5. Ruler and pencil

 

Instructions:

  1. Thinking About Your Day: Begin by considering your daily routine. Think about the activities you typically engage in during a 24-hour period. These activities could include sleeping, eating, going to school, doing homework, spending time with family, playing, and more. Estimate the number of hours you spend on each activity.

  2. Creating Your Key: Fill out the “Key” table on the top-right corner of your activity sheet. Write down each activity you identified, and the number of hours you spend on it, and choose a color to represent that activity on your graph. Make sure that the total hours in your Key add up to 24 hours, representing a complete day.

  3. Coloring Your Strip: Take a strip of paper and color in the squares according to your Key. For instance, if you spend 8 hours sleeping (represented by red), color 8 squares on your strip with the red color. Similarly, color the squares on the strip for each activity you engage in, using the respective colors from your Key.

  4. Assembling Your Loop: Once your strip is completely colored, form a loop by taping or gluing the shaded end to the back of the other end. This will create a colored loop representing your daily routine.

  5. Placing Your Loop on the Circle Graph: Place your loop on the circle graph template provided on your activity sheet. The center of your loop should align with the center of the circle. The colors on your loop should be visible on the outside.

  6. Marking Your Circle Graph: Starting with one end of color on your loop, align it with the radius on the circle graph. Make a mark on the circle at the end of each color on your loop. Be sure to label each section with the corresponding activity and color from your Key.

Remember, the size of each colored section in your circle graph should be proportional to the number of hours you spend on each activity. 

Finishing Your Circle Graph:

  1. Connecting the Marks: After you have marked each section on the circle graph with the pencil, carefully remove the loop from the graph. Now, take a ruler and a pencil. With the center of the circle as your reference point, draw straight lines from the center to each mark you made for the sections.
  2. Coloring Each Section: With the lines drawn, each section of the circle graph is now defined. Take your colored pencils or markers and color in each section according to the colors you chose in your Key. Color the sections completely to match the colors on your loop and Key.
  3. Adding Final Touches: Once you’ve finished coloring each section, take a moment to review your completed circle graph. Check to make sure that the colors and proportions accurately represent the time you spend on different activities throughout the day.

 

Congratulations! You’ve successfully created a circle graph that visually displays how you spend your time in an average day. This graph will help you visually understand your daily routine and how you allocate your time to various activities.
